Abstract. We define a notion of symmetric monoidal closed (smc) theory, consisting of a smc signature augmented with equations, and describe the classifying categories of such theo...
Abstract. We reformulate a known characterization of decomposability of polytopes in a way which may be more computationally convenient, and offer a more transparent proof. We appl...
Abstract. We start with a bijective proof of Schur's theorem due to Alladi and Gordon and describe how a particular iteration of it leads to some very general theorems on colo...
Abstract. This paper describes a proof search procedure for propositional nonclausal resolution based on a new weighting strategy that utilizes search methods for propositional sat...
Abstract. Recently M. Dritschel proved that any positive multivariate Laurent polynomial can be factorized into a sum of square magnitudes of polynomials. We first give another pro...
